MYB3 — Cucumis sativus

Summary

CsMYB3 (CSA_2G343150) on cucumber chromosome 2 encodes a Myb-domain transcription factor with sequence-specific DNA binding, protein dimerization, and small GTPase binding activities, as well as protein phosphatase activity. It is associated with the regulation of flavonoid, anthocyanin, proanthocyanidin, lignin, and phenylpropanoid metabolism, and with trichome differentiation and spacing, seed coat development, and response to iron ion starvation. The gene is linked to fruit quality, flavonoid and anthocyanin content, leaf trichome density, brassinosteroid and jasmonic acid content, UV-B light sensitivity, osmotic and oxidative stress responses, low temperature and salt tolerance, flowering time, disease tolerance, and root and shoot meristem development. Studies of related genes in other species connect the family to lignin biosynthesis, UV-B tolerance, herbivore defense, and cold acclimation.
